Abstract
The valve includes a valve body (10) with a closure member (12) and a fitting region (16) enabling the valve to be fixed, in a removable manner, to the neck of a gas container. The level gauge (20 ) is a capacitive gauge consisting of an elongate rod (24) and a cylindrical tube (22) coaxially surrounding the said rod (24), the tube (22) and the rod (24) both being supported by the valve body (10) and extending over the entire height of the container. The level measurement is based on the capacitance between the rod (24) and the tube (22) and is indicated by a display device.
